Castles & Crusades-evil and/or chaotic knights

[Mythmere1]

Has anyone given any thought to how to handle chaotic or evil knights? I posted a couple of weeks ago on the General board about knights' codes generally, and got one very good contribution of the sort of code that non-lawful aligned knights might have. It focused on the knight's treatment by the world: no one shall strike me, no one shall cheat me...

Any other thoughts on this? I know that people of any alignment can join a feudal organization based on personal loyalty, so I was thinking that anyother possibility for a knight's code might be something along the samurai model - I won't do anything that might bring dishonor on my liege lord.

Any other thoughts besides these two, or thoughts on how the character class would fit into various kinds of societies?

I would look at the Knights of Takhisis/Neraka in Dragonlance as an example of an evil knighthood. They work towards the common good, er..., evil and hold to a code of honor, much like the Knights of Solamnia.
